Abstract
Description
technical field
[0001] The invention relates to the production technology of fire-fighting air ducts, in particular to a sleeve flange module and a production line for fire-fighting air ducts. Background technique
[0002] The current processing method of the fire smoke exhaust duct (referred to as the fire duct for short in this case) is roughly as follows:
[0003] 1. Two bending plates are used to buckle each other to form a prototype;
[0004] 2. Knock the seam portion 110 of the bent plate so that the seam portion 110 bends toward the clamping portion 120 to form the first curling portion 130, and the first curling portion 130 and the seam portion 110 clamp the clamping portion 120, thereby Realize the sewing of the whole fire duct;
[0005] 3. Connect the flange 200, then drill holes on the flange and the fire-fighting air duct, and then tighten the screws to realize the flange 200 and install the flange on the fire-fighting air duct.
[0006] This method mainly has...
